The fibers used may be natural or chemical fibers and may be short fibers, filaments or fibers formed in situ. The non-woven technology is a material processing technology which is derived from textile and is higher than textile, combines the processing technology of four flexible materials of textile, papermaking, leather and plastics, and fully combines and utilizes a plurality of modern intelligent high and new technologies. Nonwoven materials are currently being used more and more, such as in the manufacture of sanitary pants for care.
In daily life, nursing sanitary trousers are sanitary articles which are increasingly commonly applied to people who cannot self-care and women in physiological periods. From the product using method, the traditional magic tape is suitable for daytime, and the waistline material with high elasticity is more beneficial to night use, but the traditional magic tape is insufficient in softness, skin foaming and other problems caused by friction in the using process, and the waistline material with soft and high elasticity is more fit.
CN105109125a discloses a preparation method and application of a spun-thermal double-component composite nonwoven material, which comprises the following steps: the first matrix layer and the second matrix layer are arranged in a stacked manner from bottom to top and are respectively formed by staggered arrangement of composite fibers formed by melting and spinning polyaniline and hydrophilic polymer; the upper surface of the second matrix layer is convexly provided with a plurality of bulges which are distributed at equal intervals, and the surface of the first matrix layer is flatly arranged; the hydrophilic high polymer is selected from one of polyvinyl alcohol, polyvinyl amide, polyvinyl acid and polyethylene glycol; the antibacterial layer is arranged between the first substrate layer and the second substrate layer.
